hi,
thinking of doing a conversion and cant find out what the standard zetec rods will take (psi). The search mentions about the pistons but not rods. Im hoping to go down the route of using c20let calibra pistons. can anybody help me with information.

cheers geoff

 

standard rods will take 300 with arp rod bolts but not worth taking the risk when you can buy steel rods for around £160 from the states

 

what psi can the c20let pistons take and what power figures would be reached with a sensible but standard build (ish) head work ect.

 

i ran 24 spi with a t34 and 19 psi with a gt 25/40r they are forged pistons so with the right mapping you could run 30 psi if you had stronger rods, 310 bhp with those pistons.

thanks

sean

 

i currently have a 1.9 power engeneering build (the 1.8 cvh crank version) what power figures is this engine capable off with management?

 

i use to run the same 1.9cvh with a decent cylinder head 300bhp the engine is quite strong.. weakest part is the cylinder liners i split mine using loads of nitrous.

thanks

sean

 

hi sean
what psi was you running, have you ever run a zetec turbo if so how would you compare them.

 

'have you ever run' sorry missed your earlyer post

 

no never run a 16v zetec just the zetec bottom end the zetec will be an all round better engine if you spend your money on the right parts.

sean

 

do you remember what boost you was running on the power engineering build or the capability that it can take. i phoned P.E and they was not all that helpful

 

the 1.9 cvh rods are only good for 260 ish bhp and steel rods for them are £700+

with the zetec block you can get forged pistons and steel rods for £500

 

hi lee are you talking about the american tall block engine. when i rang P.E they would not tell me what rods they were due to the engine being copied. its a 1.6 boared out with a 1.8 crank. i done big end bearings about 6weeks ago and sent the big ends off to be matched and they came back as the same size as bearing used on a tryumph. any more help would be appreciated
juff

 

i ran 25psi on a t34 0.63 exhaust the engine is strong just make sure you get the car mapped too much heat will cause the liners to split.

sean

 

depends if its a old pe 1.9 cvh or a newer type as the newer type are not so strong as there built at vulcan engineering

 

pe 1.9 1.8 cvh crank, triumph tr7 rods, merc mahle pistons.

 

yeah sean that sounds the one, is that the newer or older one

 

thats the older pe built one

 

has any one done a write up on this engine as i feel alittle blind not knowing any thing about it ie comp ratio

 

vulcan engineering done a write up years ago in classic ford mag i've got the mag laying about somewhere.


thanks

sean


ps i thought vulcan built all of pe 1.9cvh?

 

they did there own machine work untill about 9 years ago they also used to do good ported heads before vulcan took over doing the work

steven rw off here had a old power engineering ported head 1.6 cvh did 150 mph on 13 psi

and it it to the black top or to the silver one?

 

the rods at meant for the black top but you can sue them in the sliver top like i have.. i bought my eagle steel rods from here www.nolimitmotorsport.com £164 plus je pistons both cost me £586 all in delivered

thanks

sean
